SPECIFICATION forming part of Letters Patent N 0. 771,436, dated October4, 1904. Application filed September 10,1903. Serial No. 172,618. (Nomodel.)

1"!) MM whom, it may concern.-

Be it known that 1, ROBERT A. MOORE, a

citizen of the United States, residing at Huntsville, in the county ofMadison and State of Alabama, have invented certain new and usefulImprovements in Current Controllers for Electric Generators; and I dodeclare the following to be a full, clear, and exact description of theinvention, such as will enable others skilled in the art to which itappertains to make and use the same.

My invention is an improved current-controller for electric generatorsadapted to alternately connect generators to a line-circuit, so that onegenerator will be disused while the other is employed to furnish theline-current; and it consists in the construction and combination ofdevices hereinafter described and claimed.

The object of my invention is to combine with batteries or otherelectric generators for supplying line-current an electrically-operatedswitch and a time mechanism to control it to alternately connect thegenerators to the line, so that one of the generators will be disusedwhile the other is at work.

A further object of my inventionis to effect improvements in theconstruction of the switch employed in the vention.

In the accompanying drawings, Figure l is a diagram illustrating apractical embodiment of my invention. Fig. 2 is a detail perspectiveview of a relay-switch forming part of my invention.

In the embodiment of my invention here shown I employ a relay-switch l,the armature 2 of which operates between two insulated contacts 3 A,which are respectively connected by conductors 5 6 to batteries or otherelectric generators 7 8. The latter are also each connected to one legor wire of a line 9, the other practical operation of my inleg or wireof which is connected to the armature 2, as at 10. A spring 11 isconnected to the armature to cause it to engage the contact 3. Thewindings of the electromagnet 12 are connected to a local circuit, whichincludes a battery 13, the hour-hand 14 of a clock, anda conductor 15 onthe clock-dial, and the length of which is here shown as coextensivewith the distance between the hours 6 12, corresponding with themovement of the hour-hand during six hours. Sliding contact is effectedbetween the hour-hand and the conductor 15. The extent of the latter maycorrespond with any desired period of time, as will be understood.lVhile the ho ur-hand is in contact with this conductor the localcircuit will be closed, causing the electromagnet to be excited and thearmature forming the switch element to break from the contact 3, andthereby cut out the battery 7 from the line and to engage the contact 4,and thereby connect the battery 8 with the line. When the hour-handdisengages the conductor 15, thereby breaking the circuit of the localbattery, the spring draws the armature from the contact 4, therebycutting out the battery 8 from the line-circuit, and keeps it inengagement with the contact 3, thereby reincluding the battery 7 withthe line-circuit.

The relay is provided with suitable bindingposts a 6, connected,respectively, to the contacts 3 4 for the attachment of the wiresleading to the batteries or other generators 7 8, has a binding-post 0for the attachment of the line-wire and binding-posts (Z c for theattach ment of the wires of the local circuit, including the timemechanism and the battery 13.

From the foregoing description, taken in connection with theaccompanying drawings, the construction and operation of the inventionwill be readily understood without requiring a more extendedexplanation.

Various changes in the form, proportion, and the minor details ofconstruction may be resorted to without departing from the principle orsacrificing any of the advantages of this invention.

Having thus fully described my invention, what I claim as new, anddesire to secure by Letters Patent, is

In combination with a working circuit having a pair ofalternately-operating batteries each having one pole connected to oneside thereof, a switch-armature connected to the other side of saidworking circuit, and electrodes between which the switch-armatureoperates and each connected to one pole of one of said batteries, of atime mechanism make and break comprising a fixed conductor and a Intestimony whereof I have hereunto set traveling conductor, a spring toengage the my hand in presence of two subscribing Wlt- I0switch-armature with one of the electrodes, nesses.

and an electromagnet to engage the armature r with the other electrode,and having its Wind- ROBERE MOORE ings included in a local circuit Withthe con- Witnesses:

ductors of the time mechanism make and ED. DOUGHERTY,

break, substantially as described. 1 H. HOWARD.
